The Sedimentary Basins of the United States and Canada


Book Description

In recent years there have been rapid strides in our understanding of plate-tectonic processes, many developments in methods of basin analysis, and the accumulation of much new surface and subsurface geological and geophysical data. Projects such as COCORP (in the United States) and Lithoprobe (in Canada) have provided essential insights into the deep crustal structure of the continent. Synthesis of all the available information about North America's geological regions has not been attempted systematically since the "Decade of North American Geology project undertaken by the Geological Society of America and the Geological Survey of Canada nearly twenty years ago. The book commences with a summary of the Phanerozoic geological history of the United States and Canada, illustrated with a suite of new paleogeographic maps, and tying in each of the subsequent regional chapters by the inclusion of numerous cross-references. This followed by a set of fifteen regional syntheses of the principal tectonic regions of the United States and Canada, focusing on the stratigraphic and tectonic history of the major sedimentary basins. Most of these chapters have been contributed by specialists, drawing on their own research, and providing interpretive summaries of a type not previously attempted. - Up-to-date synthesis of the sedimentary/tectonic history of the major areas of the United States and Canada - Up-to-date references - Many new color maps




Paleoenvironmental Record and Applications of Calcretes and Palustrine Carbonates


Book Description

"This volume presents current understanding of the mechanisms and environments of the formation of calcretes and palustrine carbonates. Through a series of specific field examples, papers in this volume illustrate the wide variety of potential applications of these types of deposits. The papers presented here cover a wide array of ages and environmental settings of calcrete and palustrine deposition and include many interesting applications, such as the climatic and geomorphic controls on calcrete formation, possible modern analogues for palustrine carbonates, the interplay between palustrine, pedogenic, and diagenetic processes, the utility of radio-isotopic methods for dating pedogenic carbonates, applications to understanding landscape evolution, and reconstruction of diagenetic sequences. The result is a state-of-the-art book on these deposits so common in the geological record and in recent environments."--Publisher's website.

Field Trips in the Southern Rocky Mountains, USA


Book Description

The theme of the 2004 GSA Annual Meeting and Exposition, “Geoscience in a Changing World,” covers both new and traditional areas of the earth sciences. The Front Range of the Rocky Mountains and the High Plains preserve an outstanding record of geological processes from Precambrian through Quaternary times, and thus serve as excellent educational exhibits for the meeting. With energy and mineral resources, geological hazards, water issues, geoarchaeological sites, and famous dinosaur fossil sites, the Front Range and adjacent High Plains region provide ample opportunities for field trips focusing on our changing world. The chapters in this field guide all contain technical content as well as a field trip log describing field trip routes and stops. Of the 25 field trips offered at the Meeting, 14 are described in this guidebook, covering a wide variety of geoscience disciplines, with chapters on tectonics (Precambrian and Laramide), stratigraphy and paleoenvironments (e.g., early Paleozoic environments, Jurassic eolian environments, the K-T boundary, the famous Oligocene Florissant fossil beds), economic deposits (coal and molybdenum), geological hazards, and geoarchaeology.










Tectonosedimentary Relations of Pennsylvanian to Jurassic Strata on the Colorado Plateau


Book Description

"Following this discovery and further detrital-zircon studies of Mesozoic strata on the Colorado Plateau, Dr. Dickinson began preparing this volume in order to identify key aspects of the sedimentary and tectonic history of Mesozoic strata of the Colorado Plateau and directly adjacent areas. He divided the strata into seven depositional systems"--
